What happened might have been similar to demon possession, but other demon-possessed people are obviously unable to control any of their own actions. Here Judas Iscariot seems to do everything he desires, but Satan was somehow at work in a special way. Whatever the intended meaning, Satan "entering" Judas Iscariot is a metaphor for Satan taking control of Judas Iscariot. Alternate translation: "Satan took control of Judas, the one called Iscariot" (See: [[rc://en/ta/man/translate/figs-metaphor]])
